To save a woman trapped under a pipe, MacGyver wraps a rope around the bottom of it, attaches both fixed ends to the roof of a building, and places a stick in between both parts of the rope. By twisting the stick, he is given a mechanical advantage and is able to slowly lift the pipe up.

As a way to hold off killer ants for awhile, MacGyver makes a flamethrower out of a hose, pipe, and tank of gasoline. He also uses some "kitchen ingredients" as a fuel-thickener to prevent the contraption from simply exploding.

MacGyver and Trumbo make a nitromannite bomb by taking the nitrate from fertilizer and cellulose by mashing plant bark. The ingredients are mixed together, stirred with a drip or two of acid, then placed in a small paint can. MacGyver must walk through the ants to plant the bomb, and so makes a "suit of armor". Though it isn't stated what the material he is wearing, it is likely a thick layer of rubber from the plantation applied to cloth. He then blows up the dam, flooding the area and killing a large ant infestation, which saves Trumbo’s plantation.
